ABe it known that I, WILFRED MAJo,h a

1- of. Cook and State of cago, in the county i Illinois, have invented a new and useful Improvement in Passenger-Cars, of which the Vfollowing is a specification. c My' invention relates to improvements in passenger cars, and, more particularly, to vestibule cars, my objects, generally stated, bein to render the steps of the can converti le into platform condition and back to step condition as desired; to provide, in a vestibule car, for the operation of 4the dooiP 5 associated with the steps, to close the door when the steps are converted into a platform, and vice-versa; to provide forthe convenient oper tion of the members forming the convertib e steps and platform; to provide against the accidental displacement of the step and platform forming members; and to accompllsh other purposes, as will be manifest fromthe following description.

My invention is illustrated in its referred 5 embodiment in the accompanyingv awings,

In the drawings, I have illustrated a single one of my improved mechanisms located on one side o f one end of a vestibule passenger-car represented at 20, though it will be lunderstood that four of these mechanisms.

will, in usual practice, be provided on a car, two at each end and Vat opposite sides thereof to correspond with the 'usual location of steps on the car. The platforms at opposite ends of the car and at opposite sides thereof contain recesses extendlng transversely of the car as represented of the recess 21 in the stationary platform 22 in Fi 2, these recesses 21 corresponding wit l those commonly provided in cars of this character, and into registration with which the steps of the car extend.

In the construction illustrated,the members forming the convertible steps and platform are represented at 23, these members 110 being in the form of plates extending longitudinally of the carl andhaving eyes 24 at oppo-singedges thereof alternating with each other and through which rods 25 extend forl hingedly connecting these members together, the innermost one of the members 23 being hinged on a rod 26 stationarily secured to the `platform 22,a plate 27 having eyes 28 along its outer edge which alternate with the eyes 24 on the adjacent one f the members 23 and through which the rod 26 extends, bridging the inner end of the recess 2l. rlhe lowermost one of the members 23 is 'equipped at its under side with members 29 containing slots 30 through which a rod 31, secured at its opposite ends to depending' side plates 32, extends, the plates 32 being securedto an end of the stationary platform 22 and flanking the recess 21. it 'will thus be understood that theI members 23-hingedly connected together are hinged at the innermost ene of said members at a point in substantial alinement with the stationary platform of the car, and at the outermost one of its members is held to limited transverse displacement. by the rod 31, whereby the members 23, in unfolding them as hereinafter described to form the platform-extension, are caused to assume the position illustrated in Fig. 2. Located directly beneath 'the hinged members 23 is a frame 33 of general rectangular form which is pivoted at its inner end, as indicated at 34, on pivot-lugs 35 provided o'n `the under side of the platform 22, this frame forming the medium through which the members 23 are operated to cause them to become unfolded, preferably in opposition to spring-means hereinafter referred to, and form an extension of the plat-form 22, when the frame 33 is raised. lThe frame 33 is equipped at its outer end with rollers 36which are adapted to bear. against the under sides of the. adjacent members 23 in the folding the latter for the purpose stated.

The following is a description" of the means illustrated for raising a'nd lowering the frame 33 for the purpose hereinbefore referredto: ,Pivotally connectedatits outer end, as indicated at 37, to a depending lugy 38 on the frame 33 is an arc-shaped rackbar 39 which is movable in upwardly-.ex-

tending guides 40 carried by a bracket 41 depending from, and secured to, o ne of the longit-udinally-extending girder-beams 42 of the car, anti-friction rollers 43 being secured in the guides 40 and upon which the 'rackbar 39 moves when the latter is operated. The rack-bar 39'meshes with. aJ gear 44 fixed on a shaft 45 journaled, as indicated at 46,

in the opposed plate-members 47 of the bracket41, the shaft- 45 being also equipped with a miter gear 48 rigid therewith, this miter-gear meshing with a miter-gear 49 connect-ed withV a shaft 50 journaled inl a operation of unl depending member 51 secured to the said girder-beam and carrying-a gear 52 which meshes with a straight rack-bar 53 extending longitudinally of the car and in guides `54 supported on said girder-beam lengthhaving a rod-extension 58 slidable in a.'

sleeve59 supported and slidable in a bear-` ing 60 on a bracket 61. secured to one of the garder-beams 42,'the sleeve 59 terminating at one end in a piston 62 confined in a fluid-pressure cylinder 63 provided with a fluid-pressure control as hereinafterde scribed', said sleeve being provided at its opposite end with a head 64 circumferentially grooved as indicated at 65 and to which a pair of forwardly-extending downwardl directed arms 66 which straddle the rod 58 are secured. The member 57 carries a locking-device 67 pivoted thereto as indicated at 68 and extending rearwardly. This lock, which is normally. downwardly pressed by means of a spring 69, has its rear end bifurcated as indicated at 70 to afford a pair of depending arms 71 adapt'edto enter the grooves 65 at opposite sides of the head 64 under the action of the spring 69, and is provided on its top with a loop 72 into which the-forward end of a lever 73 proljects, this lever being fulcrumed, `as indicated at 74, on a bearing 75, secured Vto the under side of the car and provided with a depending arm 76 through the medium of which the lever 73 is adapted to raise the` lock 67 to disengage it from the head .64, as and for a purpose hereinafter explained.

The `forward end of the member 57 `is connected with the rear end of a rod 77, the latter being pivotally connected at its forward end, as indicated at 78, with a forwardly-extending lever 79 which is journaled o-ny a shaft 80 fixed to the car under the platform. The shaft 80 also forms a pivotal support for a lever 81 which is bifurcated as indicated at 82 and straddles the lever 79, the lever 81 serving as the medium' for actuating I through which the mechanism n the frame 33 is operated by hand, and in its .normal condition, namely when the members 23 are unfolded to the position shown in F ig. 2, rests against a vstop 83 secured to the under structure of the car and extends below the plane of the stationary platform 22, this 'portion of the platform being formed of a removable section 84 for rendering the lever 81 accessible for operation. The lever 81 is adapted -to be releasablyconnected with the lever 79 by any suitable means, those shown comprising a pin 85 which is slidingly confined in an opening 86 in the lever 81 and is adapted to be projected through openings 87 and 88 Iin the levers 8l and 79, respectively; a, bell-crank 4lever 89 containing a slot 92 in its forward end into which a pin 93 on the rod 85 extends and being pivotally connected at 94 l to the forward end of a link 95; and a -bellf crank lever 96 fulcrumed, as indicated at 97, on lugs 98 carried by the lever 81, the lever 96 being pivotally connected, as indicated at 99, with the rear end of the link 95 and having its opposite end, represented at 100, in the form` of a handle which extends closely adjacent to the handle 101 of the lever 81. the foregoing description of the means for locking the levers 79 and 81 together that pressin the handle 100 toward the handle 101 wil operate to withdraw the pin 85 from the openings 88 and 87, thereby disconnecting the lever 81 from the' lever 79; and that when it is desired to lagain connect together the levers 79 and 81, the operator will force the handle 100 away from the handle 101, Athereby causing the pin 85 to be projected into the openings 87-and 88, it being understood that the lever 81, before such rengagement takes place, must bein a position in which the openingsy 86,87 and 88 aline.

In the construction illustrated, provision is made for the folding and unfolding of themembers 23, as stated, and the operation ofthe vestibule-door, hereinafter described, either manually or otherwise, the particular motive power in the construction shown being fluid-pressure. To this end, the cylinder and piston mechanism, hereinbefore described, 1s employed, the cylinder 63 con`1- municating at its opposite ends with pipes 102 and 103, which communicate with op' posed ports 104 and 105 in the casing of a four-way. valve 106, the valve-proper 107 being provided with a pair of curved con- Lduits 108 and 109. The port- 110 of the valve-casing 106 communicates with a pipe 111 which communicates with a source of fluid-pressure, for example the train-line 112 forming a part of the fluid-pressure-operated brake system usually employed on cars, and the port 113 of the valve-casing 106 serves -as the exhaust. The valve structure described and which is of a well-known form is so constructed that by turning the handle 114 of the Valve-device 107, the fluidpressure fro-m the pipe 112 may be caused to iow into the cylinder through either of the pipes 102 or 103 andexhaust through the other of these pipes to the atmosphere, as will be readily understood from an inspection of Fig. 16, and is well known in the art.

In the construction illustrated, it is desired that the doors at the ends of the car be operated simultaneously with the folding and unfolding of the members 23, to cause It will be understood from ,the doors to be automatically moved to closed position in the operation of unfolding the members 23 to cause them to extend in platform-producing condition, and to be automatically swung toy open position upon .the act Vof folding the members 23 into a condition in which they form steps, and to this end the doors, such as the one represented at 11,5, are pivoted at one side at their upper 'and lower ends to the car as illustrated of the lower pivotal connection 116 of the door 115l (Fig' 9), whereby the vestibule doors 115, as 1s usual in car constructions, may be swung into and out of position the exit and entranceto the car. The lower pivot-member 116 of the door 115 is rigidly y provided with connected with a sleeve 117 an arm 118 which is pivotally connected, as indicated' at .119, with one end of a rod 120 the opposite end of this rod being pivllyl connected, as indicated at 121, with oneof the arms 122 of a T-shaped lever 123 fulcrumed on a pin 124 secured to a block y125 'on one of the plates 32. The shaft 45 is rovided with a sleeve I126 rigid therewit and containing oppositely-extending threads 127 and ,128 to which cables 129 and 130 are respectively connected, these cables connecting at their opposite ends with the other arms 131 and 132 of the lever 123.

It will be understood from the foregoing that the cable and lever connections between the door 115 and the shaft 45 operate, when this shaft is rotated, to wind either the cable 129 or 130 upon the threaded portions of the sleeve 126 and unwind therefrom the other of said cables, depending upon the direction in which the shaft 45 is rotated, the arrangement of these parts, with relation to the mechanism herembefore described for operating the members 23, being suchas to `cause the cable 129 to be wound about the sleeve 126 and the cable 130 to be unwound therefrom in the operation of the shaft 45 in a. direction to unfold the members 23 to platform-producing condition, thereby swinging the door 115 outwardly for closing the same, and winding up the cable 130 on the sleeve 126 and unwinding the cable 129 for closing therefrom when the shaft 45 is operated to cause the members 23 to fold into step condition, thereby swinging open the door 115.

It is desirable in a construction of this lcharacter that releasable means be employed for locking themembers 23 in both folded and unfolded condition, and as a desirable means for this purpose I Vprovide theconstruction illustrated and of which the fol-y lowing is a description: These means, which, in the preferred embodiment of my invention, are electrically operated, comprise a pair of bolts 133 which are guidedly confined in straps 134 secured on extensions 135 provided on the frame-member 33 and are that. the mechanism is 147, with an electric .at 151, with a lug 152'on` derstood from the @i v l t,

adapted to register with and project into openings 136 in the side plates 32 when the members 23 are folded to form steps, and` to register. with and project into openings 137 in the side plates 32 when the members 23 and frame 33 are in raised position, in which condition the members 23 -form the platformrextension; rods 138 connected with the bolts 133 and pivotally connected at their inner ends withv the opposite arms 139 and 140 lof a T-shaped lever 141 yjournaled on a pin 142 secured to a casing 143 on .the frame 33, an electro-magnet 145 in the casing 143, the terminals of which are connected, through the medium of wires 146 and push-button 148 which located at any convenient point on the car, preferably von the endwall thereof adjacent to the operating lever 81', a battery 149, or other source of electric power, being interposed in the circuit, as for example in the wire 147; an armature 150 pivot-ally connected at one end, as indicated the the casing 143 and at its opposite end' pivotally connected, as indicated` 5113.153, .with a link 154, the latter being pivotally connected atV its other end, as indicated at 155, withthe other arm 156.01 the i'shaped lever 141; anda spring 157 connected with the casing 143 and with the armature 150 and tending normally to, draw the armature 150 away from the pole of the magnet 145 and force the bolts 133 outwardly for projecting them through the openings 136 and 137 in the plates 32` when these bolts register therewith, it being unforegoing description thaty when the circuit is closed through the mag# in practice, would be net 145, the armature 150 will be attracted to the pole thereof, with the result of withdrawing the bolts 133 from the openingsin the side-plates v32 into which they extend, thereby unlocking the members 23 for permittingv them to 'be turned upon their pivotal connections with each other to unfolded or folded condition,` as desired..

The operation of the mechanism is as followsz-,Assuming the parts to be inthe positions illustrated'in Figs. 3, 10, 11, 12, 13, 14, 15 and 16, in which the members 23 are folded into a condition in which they afford steps, the vestibule-door isopen and the operating leverf 81 extends beneath the plane occupied by the stationary portion 22 of the platform, the operator, to unfold the members 23 to produce the platform-extension and close the door 115, assuming to be operated manually, removes the platform-section 84 to gain access to the lever 8-1, which latter he swings upwardly to a position in which. the pin 85 enters the slots 86 and-88 for locking the. levers 79 and 81 together. The next operation to be performed is that of unlocking theA members 23 and this is accomplished by the operator pressing the button 148, thereby closing the circuit through the magnet 145, with the result of drawing the armature 150 to the pole-piece of the magnet against-the action of the. spring 157 and withdrawing the bolts 133 from'the openings 136. Simultaneously with the pressing of the button y148 for the purpose stated, the operator swings the lever 81 dow11\fardly,the lock 67 having been preparatorily swung out of engagement with the head 64 by swinging the lever v73 upwardly, as through the medium of a cable 158 running over a pulley 159 journaled on a bearing-member 160 on one of the girderbeams 42 and connected at its opposite end with a crank-arm 161 fixed on a suitably ythe rack` 53 `forwardly, with' the result of operating the gears 52, 49, 48 and 44 in a direction to cause the se ental rack 39 to be swung to the right in Fig. 3. Thus operating the rack 39 ycauses the frame 33 to be swung upwardly on its pivots 34, with the result of causing the members 23,loy reason of their engagement with the upper surfaceof said frame, to be raised against the action of spring-meanshereinafter described, and unfolded into the condition illustrated in Figs. 1 and 2,' wherein certain of the members 23 are brought into substantial alinemen't with the fixed platform 22 and forman extension thereof, and the remainder of said members 23 depend from the outer end of said platform-extension. As soon as 'the frame 33'has moved to a position in which .the members 23 are unfolded to the position just referred to, the bolts 133, which latter during the operation of unfolding. the members 23 as stated ride at their outer ends against the inner surfacesl of the plates 32, are .projected through the openings 137 in these side plates, under the action of the spring 157, thereby lockingy the members 23 in unfolded condition (Fig. 2). Simultaneously with the unfolding of the members 23 as stated, the door 115 is swung to closed position by the rotation of the sleeve 126, which causes.

the cables 129 and 130 to be wound thereon and unwound therefrom, respectively, there. by swinging the door on its pivots to closed position through'the medium of the lever 123, link 120 and crank'118.,l rThe locking of the bolts 133 with the side plates 32 at the openings 137 as described not only serves to hold the members 23 in unfolded condition, but in addition serves to prevent actuation ofthe mechanism for operating through the platj ing i lb the frame 33 and operating the door, therebyreleasably locking the door against openthe hereinafter described means for operating the frame 33. The parts of the mechanism are so proportioned that when the lever 8l has been thrown downwardly sutliciently far to unfold the members'23 to the position illustrated in Fig.2, it will extend below the plane of the stationary section 22 of the platform and, in practice, will preferably be covered by the removable platform-section 84.

When it is desired to open the door 115 and return the members 23 to a yposition in which they form steps for lthe car, kthe operator first actuates the frame-locking devices to withdraw ,the bolts 133 ,from the openings 137 in the side-plates 32, by pushing the button 148. Simultaneously with this operation, Vthe operator swings the lever 81 upwardly, with thc result of causing the frame 3,3 to swing downwardly on its pivots 34. The support for the members'23-having been thus removed, they will fold to a condition inwhich they form steps (Fig. 3), under the action of springs hereinafter described and located at th'e hinge-connections between said members.

Swinging of the frame 33 downwardly to a position in which the members 23 are folded to form steps as stated, carriesthe bolts 133 into registration with the openings 136 in the plates 32, into which openings these bolts are automaticallyprojected by thespring 157. ln order that the lever 81 shall not obstruct the passageway of the car, it is adapted to be which it extends below the plane of the stationary platform 22 by first disconnecting 1t from the lever 7 9 by operating the hereinbefore described mechanism for actuating the pin 85 to cause the from the openings 87 and 88 in the levers 81 and 79, respectively, and thereupon swinging the lever 81 downwardly below the upper surface of In ,the operation of folding thev members 23 to cause them to assume step forkm, assuming that the fluid-pressure mechanism illus-- trated in Fig.v16 is in the co-ndition therein illustrated, namely with the pipe 103 in communication with the pipe lll-and the pipe 102 in communication with the exhaust-port 113 with {luid-pressure operating against the piston 62 to hold it at the limit of its inward movement, the lock 67 rides upon y the arms 66 to cause the bifurcated end of this lock to be raised above the plane of the head 64 and bring the loop 72 of the lock into alinement with 'the forward end of the arm 73, into which loop the lever 73 extends. ln the final mo-vement of the lock 67 in moving rearwardly as stated, the lock is projected downwardly under the action and operates to prevent strain againstA moved to a position inl latter to be withdrawn the stationary plat-form 22.l

of the piston 62 dropping into the of the spring 69 to cause the arms 71 of this lock to extend into the grooves 65 of the head 64, as illustrated in Fig. 12.

In the o eration of the mechanism for folding an unfolding the members 23 and swinging the door to open and closed positions by other than manual power, as/ for example by the piston 'and cylinder mechanismillustrated in Fig. 16, thelock 67 serves as the means for connecting the piston 62 with the rack 53 for actuating the latter by the reciprocationg of thepi'ston. It will be readily understood from the foregoing description and the drawings that when the valve 107 is rotatedy to cause the pipe 102 to communicate with the source of iuidpressure through the pipe lll and the pipe 103 to communlcate with the exhaust-port 113, fluid-pressure will be admitted into the y rear end of the cylinder 63 behind the piston 62, with the result of causing the rack to bemoved to the right in Flg. 10 for swinging the frame 33 upwardly to unfold the steps into platform-producing condition and close the door 115; and when the valve 107 is rotated to the position illustrated in Fig. 16, fluid-pressure will be introduced through the pipe 103 into the front end-of the `cylinder 63 and in front of the piston 62, with the result" of returning the rack 63 to the positionillstrated in Fig. 10, thereby causing the members 23 to fold into step condition and effectin the opening of the doo-r 115'. It will be un erstood that in the operation of the door opening and closing and conve'rtible step and platform operating mechanisms, through the medium of the fluidpressure mechanism described, the described locking mechanism for the frame 33 must first be actuated to withdra-wthe bolts 133 from those of the openings`136 and 137 in the side plates 32 in which these'bolts eX- tend, as will be manifest from the foregoing description.

Should it be desired that the sure mechanism be connected up with the rack 53 when the members 23 are unfolded, in which condition the rack will be projected tothe right in Fig. 2, and the lock 67 at its bifurcated portion will .be out of engagement with .the head 64 and be spaced therefrom, the valve 107 will be rotated to cause the yfluid-pressure to enter into the rear luid-pres- Y end ofthe cylinder 63, thereby forcing the sleeve 59 and' the head 64 to the right in Fig. 12, with the result of causing the arms 66 to engage with the lower ends of arms 71 of the lock', the arms 71 riding upon the arms 66 and in the final forward movement groove 65. It will be understood, however, that before the valve`107 is rotated to cause the piston to be forced -backwardly for folding the members 23into step condition, the lever 81 should' be disconnected from the lever 79 by withdrawing the pin from engagement with the lever 81 in a manner hereinbefore described.

I -referto employ spring-means, here- V- inbe ore referred to, tending to fold the members 23 into step-forming condition, and as a desirable form of means for 4this purpose I provide those illustratedv and of which the following is a description: Each of the members 23 is provided at opposite ends with bars167secred to the' under sides thereof, these bars being` provided at their opposite ends with circular heads 168 and. 169. The heads 168 contain outwardly; opening annular recesses 170` are circular in cross-section, extend into the annular recesses 170 in the adjacent heads 168 as represented in Fig. 6 of the construction therein shown, the outer ends of the sleeve-sections" 171, a portion of the wall of each recess 170 being cut away at an angle somewhat in excess of 900, as illustrated at 172, in order that the heads 169 and 168 may intert with each' other as described and be relatively movable in the folding and unfolding of the members 23, for the purpose hereinbefore described. The provision of the recesses 172 aords shoulders 173 and 174, certain ones of which engage with the bars 167 adjacent to the heads 169 when the members 23 are unfolded to extend in platform-producing position as represented in Fig. 2, and 'the other ones of which engage with the bars- 167 when the members 23 are folded into a condition. in which they form steps as illustrated in Fig. 3. Each of t-he sleeves 171 is surrounded by a coiled spring 175 which isT connected Vat one end, as indicated at 176,

with the head 168 and at its opposite end is connected with the head 169 as represented at 177. Alternate springs l175 at the sides of the convertible step and platform-exten-sion members are wound in opposite died to seat when the members,23 fold into' step condition, under. the action of the springs 175, as illustrated-in Fig. 3.

lIn order 'that the `members 23, when moved into step-condit-io'n, be heldragainst under sides of certain of the surroundingi sleeve-sections 171 on the heads 168 and -through which the respective rods 25, at' their ends, extend. The heads 169, whichand are journaled upon menace accidentaldisplacement,- I provide on the members 23, at opposite sides thereof, clips 164 having Iinwardly-directedl flanges 165 which 4overlap flanges on' the frame 33, said clips,

when the members 23 are in step-condition,

fitting closelyagainst the flanges 165 (Fig. 3) and preventing the unseating of the members 23 from the lugs 178 and 179, it

being understoodthat when the member 33 (Figf3) and the members 23 form steps, the bolts 133 are in engagementy 1s depressed with the side-plates 32 and thus pressure on the operating mechanismfor the members 23 is avoided. The clips 164 also serve, in case anyA obstruction to the members 23 is presented, to insurev the movement 'of the members 23 to folded condition upon lowering the frame 33. 'The hinged connection of the series of members 23 with the rod 31 operates to hold said series at its lower end, in order that the members 23' position to the action of the springs 175, when the frame 33 is raised, to produce the platform-extension and depending section therefor illustrated.

l'n practice it would be desirable to have the folding of i properly unfo-ld in opi the step-and-door operating mechanisms under, control of an authorized person, only, on the car, and to this end the push-button mechanism described may be contained in a box not shown), which would have a removable closure controlled by a lock, or the operation of the push-button may be other- .wise controlled, or the control for the airpressure to the cylinder-mechanism may be under lock and key or both of saidmechanisms may be so controlled. ln fact, any desirable means which will ent to any one skilled in the art, `may be employed for preventing any other than an authorized person from operating the stepand-door operating mechanisms.

By equipping a car with step-members as described, and especially where they are unfoldable to form a platform-extension and a depending section as illustrated, danger of accidents to persons is greatly minimizedwhen the steps are up and the door closed,

as no one can alight from the car and no step 'is presented at the outside of the car upon' which a person can stand. Further'- more, dangery of soiling the clothes of passengers entering, or alightingk from, the car when the stepsl are down, is avoided, as no surfaces of the passageway of the car are exposed to the dirt during the running of the train, as distinguished from the condition in vestibule-cars as commonly used, wherein dirt and snow lodge on the steps and the undersides of thetrap-doors, which latter, when the exit is open, are thrown back and exposed.

By my improved arrangement, the steps readily be apparreeA its

may extend flush with car, which thus permits the steps to `extend the outer sides of the lower down than in the case of the cars as .usually provided wherein the steps reach a suiiicient distance short ofthe car-sides to render it diiiicult for one to stand on the steps on the outside of the car when the door is closed,/thus causing the steps to reach short of the desired distance from the ground and requiring the use of a stool to aid passengers in alighting.

While I have illustrated and described a specific form of construction constituting an embodiment of my invention, I do not Wish Ais movable members to be understood as intending to limit it to such construction, as the same may be variously altered and changed without departin from the spirit of my invention.
